I have a brand-new geothermal furnace installed by RB Heating Climate Care and am a happy customer. I shopped around and found RB's package had the best price for my preferred bundle of options. It is an expensive unit that I expect will save me some money in the long run. RB did a nice, professional job. Everything went as scheduled. It was installed in September, so I've had a chance to use it and it provides a warm and stable temperature for my home. Five stars for RB Heating Climate Care. I recommend them highly!
